[asterisk-users] Usage of lock in CDR

[Nikhil]

Hi Lesher

Thanks for reply. I am trying to understand how CDR in asterisk is 
working(Code wise),because some issue are there in  CDR in call feature 
scenarios like call transfer ,call forward etc.I wanted to fix that 
issues for that I am planning to rewriting the CDR logic.Do you have any 
document which explain how CDR works in asterisk and what are its 
limitations.

Thanks

Nikhil
